CUOZZO Feb. 11, 1936 METHOD OF AND APPARATUS FOR ATTACHING SHOE HEELS Filed Jan. 10,, 1934 3 Sheets-Sheet 3 Patented Feb. 11, 1936 UNITED STATES PATENT OFFICE LIETHOD OF AND APPARATUS FOR ATTACHING SHOE HEELS Michele Cuozzo, Lynn, Masa, assignor to United Shoe Machinery Corporation, Paterson, N. 1., a corporation of New Jersey Application January 10, 1934, "Serial No. 708,000 23 Claims. (01. 12-141) gether, and then,'at a later time, as after an adhesive interposed between the heel-seat of the shoe and the heel-cup has hardened, to remove this temporary securing means and substitute a permanent fastener.

15 An object of my invention is to simplify and render more efficient the above-indicated procedure. To this end and in an improved method of heel-attaching, I utilize the same fastener, as a wood screw, to perform both temporary and permanent securing operations. First, it may be caused to urge the heel, shoe and its contained last toward one another, as by its entrance into the heel and the reaction of a head which it bears against a part of the last. Then, after the desired interval, which, for example, may be sufficient for the heel-securing adhesive to set, and during which various making operations may be performed upon the work, the last is released from the fastener, which is thereupon employed so as a part of the shoe-structure. Preferably, to receive the fastener initially, a hole is drilled through the shoe-bottom into the heel, and to protect the heel-seat-material against being cut by the fastener during the final attaching operav 35 tion, a washer may be inserted between the fastener-head and the inner surface of the heel-seat after the last has been released from the fastener.

The invention has as another object the provision of means by which my improved method 40 may be performed. This comprises, more essentially, a last through the heel-seat portion of which opens a passage to receive the fastener which is to be used, there being mounted at the heel-seat end of the passage a member which is 45 movable upon the body of the last into and out of position to be engaged by the fastener. Thus, for. the step of temporary attachment of a heel, the member may be caused to assume a relation in which a. portion of the fastener, as'its head, 50 may contact with the member; while for the permanent use of the fastener, the member may be moved from its retaining position so the last may be removed from the shoe, and the fastener set firmly in the work. Herein, the member is shown 55 as movable in a space between the last-body and a. heel-plate secured thereto, it containing an opening, one portion of which will permit the fastener-head to pass, while another will retain said head, and thus furnish an abutment to which the reactive force of the fastener is ap- 5 plied.

Herein, I have disclosed certain steps in the process and one embodiment of apparatus desirable for use in carrying the process into effect,

but wish it to be understood that other and 10 equivalent apparatus may be employed for the purpose, and thatother and equivalent process steps may be substituted for those specifically illustrated and described herein. Another species of theapparatus is made the subject of an ap- 5 plication for Letters Patent, filed in my name in' the United States Patent Oflice on July 16, 1935, the Serial No. being 31,647.

Referring to th e drawings, the numeral I designates a shoe last which may be of the usual type except for such modified-details of construction as are hereinafter described as pertaining to the present invention. In this last is a spindle hole 2,. preferably provided with a metallic liner 3 and the rear part of the last is furnished with a rfail clenching plate 4 which may be secured by screws 5. This plate is provided with a central opening 6 commonly used to permit the rear assembling tack to be driven into the wood of the last. In accordance with this invention the opening 6 is in axial alignment with the spindle hole 2. The plate 4 is also furnished with a hearing opening I here shown as located between the rear fastener 5 and the hole 6. At the rear of the last is a bore 8 extending vertically through the top 9 of the cone, this bore being'provided with an enlargement I 0 adjacent to the surface 9.

Between the plate 4 and the body of the last is a shallow cavity ll (Figs. 6 and 7) for the reception of a movable abutmentplate l2. This plate, as illustrated in Figs. 8 and 9, is fixedly united to a stem or shaft l3 which i journaled in the ope g 8 in the last. The stem projects into the enlargement Ill of the opening 8, where it is arranged for engagement by a key l5 (Fig. 8a). The stem I3 is preferably extended at I beyond the plate I2 and this extension I8 is journailed to turn in theopening I. of the plate 4. The plate l2 has a slot or opening preferably ofkey-hole shape, having a-substantially circular head portion I! at one end and a narrow tail portion l8 extending laterally therefrom. This tail portion is curved on an arc concentric with the stem I 3, and its extreme end may be countersunk or beveled, as shown at H, at-that side of the plate which is nearest to the top of the last. As illustrated in Figs. 10, 11 and 12-, the plate l2 may be made independently of the stem I 3 and in this event I prefer to provide the plate with .an opening 20 ofpreferably toothed conthe stem with an enlargement 2| of similar contour and adapted to fit within the, opening. The stem l3 has a projection l6" beyond the enlargement 2|, adapted to turn in the opening 'I- of the plate 4. This arrangement provides a reliable connection between the stem, l3 'and the plate l2. In a preferred construction, the edge of the plate,'whateverits connection 'to the stem, preferably has a pairiof which maycooperate ,with the rear screw 6 to limit the rotation of said plate in either direction. My improved method may be carried .out in connection with the described last substantially as follows: InFlg. lo I have illustrated an insole S and an upper U assembled 'in lasted relation, with the margin M of the upper turned over onto the under surface of the insole and united thereto action and to drawthe heel firmly against by lasting tacks. The upper U, as here referred to, may be understood to include an outer element, 9. lining, doubler, and counter, if such parts be employed, and it will be understood that if the present invention be applied to shoes of other types, for example, turn shoes, wherein but a single sole is employed, the present method will be modified, as will be obvious to those skilled in the art, in such particulars as may be necessary to conform it to the particular type of shoe being made. As illustrated herein, the shoe may be considered as of McKay type, having an outer sole 0 secured to the lasted insole and upper, and the rear part of this outer sole may be beveled at its edges to provide a heel-seat for the concave upper surface of a wood heel Having prepared the shoe by usual methods, as above outlined, and assuming that the shoe is otherwise ready for application of the heel, I next prefer to apply a coating of glue or other adhesive G (Fig. 1) to the heel-seat surface of the sole or to the cup of the heel, or to both, and having placed said heel in contact with the heel-seat of the sole.) I clamp it firmly in place, preferably by mechanism such as hereinafter described. At this time the last I is within the shoe, and the next step in the process consists in introducing a drill D (Fig. 1a) through the spindle hole 2 of the last and causing said drill to form a bore 22 extendcomplished by the application of such a tool as,

a key I! tothe end ll of the stem l3. Theboring having been completed, the plate is shifted to bring the tail, l8 of the slot over the spindle opening, and such a fastening device o'rfastener,

as a wood screw F- (Fig. 2) having a slotted head E, is placed in the bore 22, for example with the assistance of a magnetic screw driver M. This screw is now turned until its head is set firmly against the abutment walls at opposite-sides of 5 the slot IS, the beveled surface of the seating upon the inclined (wall H at the end of the slot,

The screw F should be of such length and diameter as to provide a secure anchorage for the heel;

Since a hole is first drilled in the heel for the reception of this screw, there is little danger of splitting the heel in inserting the screw, although the latter may be of substantial diameter andof considerable length. Since the head of the screw bears against the abutment plate l2 and since the latter is held against displacement within the last in the space II, it is possible to so drive the screw as to exert a very powerful clamping the heel-seat with sufllcient pressure'to enable the glue, while setting, to develop its maximum holding power.

' The screw driver is withdrawn from the spindle-hole 2 after the screw has been set in the position of Fig. 1. and the shoe may be now finlshed, including such further operations ,on' the heel as maybe necessary; When the shoe is substantially complete, the operator turns the stem It, by means of the key l5, to swing the plate I 2 back to the positicn shown in Fig. 7.] If necessary,-the screw F may be backed of! slightly so as to free the abutment plate to allow this movement. It is now possible to withdraw the last from the shoe, since the head E of the screw is free to pass through the head "of the keyhole slot in the plate. The screw F may now be turned into final position, and while it is not wholly necessary, by reason of the firm attachment of the heel to the shoe by the interposed glue, I prefer, in performing this final setting upof the screw F, to hold the heelfirmly clamped against the heel-seat of the shoe. To distribute the strain imposed upon the sole by the head of the screw while the shoe is being worn, I may at this time insert a washer 'W (Fig. 13) which is slipped under the screw head E just before the latter is finally set. Preferably this washer has a countersink W so that the screw head may be brought down flush with the upper surface of thesole member. The slip sole K (Fig. 4) is now inserted in the shoe in usual fashion, its rear end covering the head of the screw and the washer.

' To assist. in carrying out the above operations I may, if desired, provide a machine such as illustrated in Fig. 14. This machine comprises a base 23 having a substantially vertical standard 24 and a post 25 secured to the standard by brackets 26. On the post 25 are brackets 21 having aligned bearings for a vertically slidable jack spindle 28 on the upper end of which is mounted a shoesupporting jack 29. This jack preferably has an upright portion 30 provided with a suitable pad for engagement with the rear surface of the shoe heel and with a bearing 3| for a vertically adjust able toe support 32. The jack also comprises a heel supporting member 34 pivoted at 33 to swing about a horizontal axis and having a rear portion 35 preferably furnished with a pad on which the heel of the shoe may rest. The part- 35 rests upon a very stifi spring 36 adapted to allow slight yield of the shoe sufficient to avoid breakage of the heel during the operations to be performed. The jack spindle is furnished with a. series of ratchet teeth 31 engaged by a pawl 38 to retain the spindle in vertically adjusted position, the pawl being disengageable from the teeth 31 by a lever 39- At its lower end the spindle 28 is pivotal;- ly connected to a tread-lever 40 fulcrumed at 4| between brackets carrried by the base 23 and having a foot-pad 42 by which the operator may rock the lever and thus raise the jack.

Above the normal level of the jack 29,'the post 25 carries a yoke 45 comprising spaced arms 43 and 44 adapted to engage the upper part of the last at the heel portion thereof. Preferably the end portions of the arms 43 and 44 are adjustable and may be retained in position by means of a bolt 46. A bar 46 carried by the adjustable end portions of the arms is arranged to bear down upon the top f the last cone. The yoke is constructed to withstand upward pressure, exerted by the operator through the treadle 42 and spindle 28. Above the yoke 45 is a sleeve 48 rotatable on the post 25 between a pair of fixed collars 43 and 50. The member 43 has fulcrumed upon it a pair of vertically movable levers 5| and 52 normally held up in inoperative positions by springs 53 and 54. The lever 52 supports a drill mechanism 55, which may be of the helical type or motor driven. This mechanism actuates the drill D. The lever 5| carries a screw driver mechanism 56 which may be helical or motor driven and includes the. screw driver M. Since the member 43 may turn on the post 25, it is readily possible to bring either the drill n or the screw driver M into vertical alignment with the spindle hole 2 of the last upon the jack 29, so.

that the drill and the screw driver may alternatively be. placed in operative position. The levers 5| and 52 may comprise relatively adjustable parts to conform to shoes of different sizes. The mode of use of the machine is so obvious in view of the above description of the method,

that is not necessary to go into further detail.

As previously pointed out, it is desirable, when setting the screw F into its final position after withdrawal of the last, to clamp the heel firm- 1y against the shoe bottom, and the mechanism shown in Fig. 14 may be used for this purpose as well-as in the drilling of the heel and the initial setting of the screw. To facilitate the clamping of the heel during the final setting of the screwImay.if desired, provide an auxiliary clamping element 51 (Figs. 2, 3 and 15) which may, for example, be secured to the yoke 45 by means of the bar 46 above described. This clamping member 51 is preferably of substantially U-shape in horizontal section and is adapted to fit within the rear part of the shoe with its lower edge resting against the upper surface of the insole, leaving a free space for the passage of the screw driver M. Thus in performing the final operation of setting the screw, the shoe from which. the last has been removed is placed on the jack in. the position shown in Fig- 14, and the jack is elevated until theinsole is pressed against the lower edge of the memb r 51, as shownin Fig. 2. The heel is thus firmly eld against the shoe and screw driver M may now be operated to set the screw to its final position without disturbing the adhesive joint. While it is possible to apply the clamping member 51 to the apparatus of Fig. 14 prior to each final setting of a retaining screw F, I may find it preferable, when making any substantial number of shoes, to provide two separate machines, one being furnished with the clamping member 51 but without the drill and screw driver, while the other has such operating mechanisms without the clamping device.

' As an alternative mode of procedure, I may, instead of the movable abutment plate [2, provide the last with a fixed abutment. For example, the hole 6 in plate 4, may be of such diameter the shoe, and the subsequent reinsertion of-the screw in the hole already made in the heel (now firmly united to the shoe bottom by adhesive). The reinserted screw would then be set to final position, following the procedure already outlined and illustrated in Figs. 2 and 3, it being possible under the modified method to employ a washer of complete annular form. While this last described method results in a completed shoe having the same characteristics as that resulting from i the first described procedure, it is somewhat slower, so I prefer'the latter.

inserting a fastener element from the interior of the shoe through the shoe bottom and into the heel, causing the fastener to react against a part of the last, thereby to draw the heel toward the last and to press the heel firmly into engagement with the heel-seat surface of the shoe bottom,

'thus maintaining such engagement of the heel and heel-seat while performing subsequent op erations on the shoe, and employing said fastener as a means for permanently uniting the heel to the shoe bottom.
